Overview of this book

The volume, diversity, and speed of data available has never been greater. Powerful machine learning methods can unlock the value in this information by finding complex relationships and unanticipated trends. Using the Python programming language, analysts can use these sophisticated methods to build scalable analytic applications to deliver insights that are of tremendous value to their organizations. In Mastering Predictive Analytics with Python, you will learn the process of turning raw data into powerful insights. Through case studies and code examples using popular open-source Python libraries, this book illustrates the complete development process for analytic applications and how to quickly apply these methods to your own data to create robust and scalable prediction services. Covering a wide range of algorithms for classification, regression, clustering, as well as cutting-edge techniques such as deep learning, this book illustrates not only how these methods work, but how to implement them in practice. You will learn to choose the right approach for your problem and how to develop engaging visualizations to bring the insights of predictive modeling to life

Chapter 2. Exploratory Data Analysis and Visualization in Python

Analytic pipelines are not built from raw data in a single step. Rather, development is an iterative process that involves understanding the data in greater detail and systematically refining both model and inputs to solve a problem. A key part of this cycle is interactive data analysis and visualization, which can provide initial ideas for features in our predictive modeling or clues as to why an application is not behaving as expected.

Spreadsheet programs are one kind of interactive tool for this sort of exploration: they allow the user to import tabular information, pivot and summarize data, and generate charts. However, what if the data in question is too large for such a spreadsheet application? What if the data is not tabular, or is not displayed effectively as a line or bar chart? In the former case, we could simply obtain a more powerful computer, but the latter is more problematic. Simply put, many traditional...
